BIBLIOGRAPHY OF PALASOZOIC CRUSTACEA 113 
ULRICH (E. O.) and BASSLER (Ray S.)—Continued 
Kloedenella new genus. Genotype Aloedenia Pennsylvanica Jones. 
The genus includes some 8 to 10 species, two of them probably only varieties rang- 
ing in time from the Clinton to Middle Devonian. ‘The British species Beyrichia ? 
bicaesa J. &. K., may be included. 
This genus is divisable into two sections: 
In the first, the genotype, the posterior and median furrows are shorter than in sec- 
tion number 2, and the anterior furrow either wanting or more or less well-developed. 
In the 2nd section, of which Beyrichia Halli Jones, is a good example, the posterior 
and anterior furrows are long, subequal and extending nearly or quite across the valve. 
Kirkbyina new genus. Genotype Beyrichiella ? reticosa Jones and Kirkby. 
Kirkbyina resembles Primitia, but is readily distinguished by its overlapping valves 
and thicker anterior end. 
Beyrichiella J. & K. Genotype B. cristata J. & K. 
The shell is relatively longer than that of Kirkbyina, and its larger valve is not 
the right, as in that genus, but the left. 
The authors include under Beyrichiella B. cristata and Kirkbyina annectens the type 
of Synaphe Jones and Kirkby, also Ulrichia confluens Ulrich. 
The generic term Synaphe was used by Huebner, therefore preoccupied. 
Beyrichiopsis J. & K. Genotvpe, B. fimbriata J. & K. 
Other typical species are the Carboniferous species: 
Beyrichiopsis cornuta, B. subdentata, B. fortis, B. granulata and B. simplex, all de- 
scribed by jones and Kirkby. 
Jonesina new genus. Genotype Beyrichia fastigiata J. & K
